'CODE PRINTING APPARATUS Filed May 29, 1955 v '7 Sheets-Sheet 7 reameam. ia 19 This invention relates to a telegraph 4printer and moreespecially to a certain improvement on the type of printer shown in thepatent to Morton, 1,791,740 of Feb. 10, 1931, and is adaptedto beoperated and controlled by the transmitter shown in my copendingapplication, Serial No. 1,148 led January 10, 1935.

It is an object of this invention to provide a telegraph printer adaptedto be operated toprint a character comprising a set of from one to ilveimpulses, with a ixed impulse for actuating the shift mechanism of theprinter and at the same time printing on the control sheet reproduced bythe printer, a shift impulse control character.

The mechanism herein shown and described can 1 likewise be operated bythe conventional perforated tape transmitter sending up to ve impulsesfor each character and in the eventl of the use'of a tape transmitterfor controlling the herein described apparatus the separate shiftimpulse transmitted by the tape transmitter of course operates the shiftmechanism and causes the herein shown and disclosed mechanism to printthe shift code character on the control sheet upon operation of theshift mechanism oi the printer. It is another object of this inventionto provide a telegraph printer adapted to be controlled by a set ofelectrical impulses for reproducing a printed sheet preferably to beused for the controlling of other transmitting machines or which may beplaced in a line-casting machine, typesetting machine and the like asdisclosed in my co-pending applications, Serial No. 404,331, led Nov. 2,1929, and Serial No. 517,171, iled Feb. 20, 1931, and Serial No.688,753,led Sept. 9, 1934.

It is a further object of this invention to pro` vide a telegraphicprinter having type bars for printing legible charactersan'd having.means op erable upon actuation of a type bar for printing a codecharacter in association with thelegible characterl written by the typebar, but printingI the c ode character by means entirely remote from thetype bar.

It is still a further'object of this invention to provide a telegraphprinter having a plurality -of type bars adapted to be actuated by meanscontrolled by sets of impulses transmitted to the printer for printingon a suitable sheet the legible characters appearing on the type barsand having a plurality of means controlled by the selection of a typebar for actuation; and adapted to automatically print a pre-determinednumber of cell controls on the sheet in association with the legiblecharacters printed.

There are many advantages of the therein disclosed and describedapparatus over and above the apparatus shown and described in mycopending applications, 426,854, led Feb.7, 1930; and 546,380, med June23, 1931; and 712,065, led Feb. 19, 1934. In the three mentionedco-pending patent applications, the type 'bars for printing the legiblecharacters had one or more raised projections thereon for printingsimultaneously with the printing of the legible character one or morecell controls for controlling a character reproducing machine, such astelegraphic printer, type-setting machines and the like. By having thecell controll printing projections disposed on the type bars printingthe legible characters, it

often happens that the type bars in the type; writer get out ofalinement and this causes the cell controls to be printed on the controlsheets\ slightly out of alinement. On account of the fact that thephoto-electric cell scanning mechanism in the character reproducingmachines set forth in the above mentioned applications, travels along apredetermined path, it sometimes occurs that the cell controls will notbe in direct alinement with the scanning means, resulting in amis-selection in the character reproducing machine. By providingseparate code printing means to print one or more cell control shadedportions on the control'sheet while the type bar prints the legiblecharacter, perfect alinement of the code character isv obtained. Thefact that the legible character is not in alinement makes no diierencein the selection ma de by the control, sheet placed in a characterreproducing machine because as previously pointed outin said co-pendingpatent applications, the legible character plays no part in the controlof tlfe character reproducingl machine but merely acts asa guide inproof reading the rcontrol sheet and for editing purposes.

Perfect alinement of the cell controls on the code sheet reproduced bythe herein disclosed printer is obtained on account o f the cell controlprinting members having a very short stroke vand being disposed in closeproximity to the control sheet at all times, whereas, the swinging typebar in the conventional typewriter or telegraphic printer has a longstroke with a pivot point removed several inches from the point ofcontact with the control sheet. 'Ihis may permit variation in the pointon the control sheet at which the cell controls are printed, whereas,inthe present instance the cell controls are placed at the exactposition desired and therefore the scanning mechanism in the characterreproducing machinel which scans the.control sheet produced by theherein disclosed printer is in perfect alinement with the cell controlsand therefore perfect results are obtained by the character reproducingmachine.

A still further object of the invention is to provide a telegraphicprinter, typewriter and the like, having means for printing legiblecharactersv and having other means for printing cell controls and alsoprovided with means for automatically printing a shift character uponactuation of the shift mechanism'of the printer.

A still further object of the invention is to pro- .vide in atypewriter, means for preventing the printing of any character in thefirst letter space of a line when the carriage is returned to startingposition.

It is a further object of this invention to provide in a typewriter aplurality of push bars operated by a striking bail and providing meanscontrolled by certain of said push bars when actuated for anon-character printing operation to prevent the printing of any cellcontrols on the control sheet during the actuation of said special barsfor a non-character printing operation.

Referring more specifically to the drawings, the numeral II) indicatesportions of a telegraphic printer frame as is disclosed in the abovereferred to patent to Morton. This telegraphic printer has a drive shaftI I driven by any suitable means such as disclosed in said abovereferred to patent, and has the conventional cam I2 on the end thereofwhich, in said patent, is connected to suitable levers, not shown, vforlocking the permutation bars against moving when the push bars foractuating the type bars are allowed to move against The said Mortonstructure also has permutation bars which are indicated in thisapplication by reference characters I, 2, 3, 4 and 5. The Mortonstructure also has a plurality of push bars I5 for actuation of the typebars and additional push bars I6, Il, I8 and I9 for carrying out certainnonprinting operations as will be hereinafter described, saidnon-printing push bars, all being conventional, in the Morton patent.The re-set bail 20 is adapted to normally hold the push bars away fromthe permutation bars. After a predetermined number of the permutationbars have been actuated,'the releasing bail 20 is moved upwardly toallow one of the push bars to move into a set of coinciding notches inthe bottom of the permutation or selecting bars, said release bail beingactuated by conventional means shown in said Morton patent. to I9inclusive, is provided with a spring as indicated by reference character2I in Figure 1 of said Morton patent, for normally moving the push barsupwardly into contact with the permutation bars and the reset bail 20normally holds the push bars against thoe tension of their associatedspring and prevents engagement with the permutation bars. The push barsare actuated when Each of the push bars I5,

one of them moves into a set of notches in the permutation bars by meansof bail 22 which is also indicated by reference character 26 'in saidMorton patent.

The said telegraphic printer is also equipped with a suitable carriagemechanism 23 having a suitable platen 24 therein which is equipped ateach end thereof with perforating mechanisms for perforating themarginal portions of the control sheet as it is printed. Thisperforating mechanism is shown and described in detail in my co-pendingapplication, Serial No. 712,065, and a description of the same is notdeemed necessary in the present application. The permutation bars 1 to 5inclusive are moved selectively in the conventional manner to the rightin Figure 13 and towards the observer in Figure 12, by conconventionalstriking 1 l5 upward movement of release bail 20. This causes trolled byimpulses coming from a tape tr mitter or from a transmitter shown in mycopending application Serial No. 1,148, illed'Jan.

vallowed to move upwardly by the conventional mechanism, the lever ofcourse swings on its pivot to cause the free end thereof to follow thelever 25 to move away from one end of the bell crank leversla to 5ainclusive pivoted as at 28 in a comb 29 disposed on the exterior offrame ill.

The bell cranks ia to 5a each have a projection thereon which is adaptedto engage the i lower edge of a permutation bar when the bar is moved byan impulse. The permutation barsvi to 5 which have been moved willprevent the corresponding bell cranks ia to 5a from rotation.

The outer legs of the bell cranks la to 5a inclusive, project downwardlyand are adapted to be engaged respectively by the rear end of levers Ibto 5b inclusive. Bell crank 5a is not controlled by the permutation barsI to 5, but is controlledv by the basket shift mechanism to behereinafter described.

The levers ib to Sb inclusive are pivoted as at di between outstandingprojections 22 and 33 projecting from a plate 34 secured to the frame orthe typewriter. A Projecting from the end portions ot plate are combs 35and 35 in which the levers ib to 5b inclusive are mounted for slidingmovement. The forward ends of levers ib to 5b inclusive, except 5b, haveeach a tongue 3l thereon and are adapted to engage the lower A ends ofupstanding levers ic to 5c respectively.

These levers ic to 6c inclusive, are pivoted as at 38 betweenprojections 35 and 45 projecting outwardly from a plate #il secured tothe printer frame. The plate 4| has projecting from the upper and lowerends thereof combs 42 and in which levers ic to 5c inclusive areslidably mounted. These levers ic to 5c inclusive are normally .pressedin a. counter clockwise. direction in Figure 2 by means of each of saidleversv having a lug 44 thereon having secured thereto a tension spring45, the other end of which is connected to a pin 45 secured in frame.

The other end of levers le to 5c inclusive, are normally held inengagement with levers -Ib to 5b inclusive, by means of springs 45. Thetension springs 45 also hold the upper ends of levers le to 5cinclusive. in close proximity to the ends of code printer locking barsid to 5d inclusive. thus holding the upper ends of the plate 52 to whicha tension spring 53, for each of the vprinter locking bars, is secured.v'I'he other ends of said tension springs aresecured to the .codeprinterlocking bars to normally force the the typewriter Y bars lc to 5cinclusive., slightly removed from -the printerfrom bracket 50 is a comb55 in `which are slidably mounted the left-hand ends of printer lockingbars 3d, 4d and 5d. The printer locking bars Id, 2d and 5d bow upwardly'in order to pass over comb 55 and the right-hand code printer bars 3e,4e and`5e then extend downwardly and are slidably mounted in a comb 55projecting Aupwardly from the lett-hand end of bracket 55 as f' seen inFigure 2. Combs 55 and 55 have suitable cap plates 51 and, respectivelyfor`loosely confining the printer locking bars in position in said,combs.

' Bracket 50 has mounted on the upper side thereof a comb 50 in whichare slidably mounted the code printer bars 2e. ie and 5e, reading fromtop to bottom. Comb 55 has an L-shaped member 50a secured thereto toloosely confine the code printing bars 2e, I e and 5e respectively, inposition therein.

Eachl of the code printer bars has a notch 55 in the right-hand sidethereof as seen in Figure l, of diierent lengths to receive the lockingbars 2d, Id and 5d respectively, when these are moved to lock the codebars against a printing operation.

ri'he ends of the code printing b ars disped next to the'platen 24 areguided in a suitable comb 5| disposed on the upper end of a bracket 62secured to the frame ofthe typewriter. This comb has a plurality ofparallel horizontally disposed slots for receiving the forward end of'the code printing bars and it also has a vertically disposed rib 53 forguiding he code printing bars in theirmovement which is adapted to fitinto slot 54 in the ends of code printing bars 2e, ie and 5e. Each ofthese code printing bars 2e, le and 5e have laterally disposedprojections a dot or cell control on the control sheet immediately belowthe printed legible character whichv is printed by the conventional typebar. This pear Aand the face of the type bar is cut away as at 55 and15, to prevent the type face from striking the front side of theprojection 55 in a combined code printing and character printingoperation. y

Bracket 50 has projecting upwardly therefrom a comb I5 in which the code.printing bars 2e, 4e and 5e are slidably mounted. l These bars,likewise. have notches I54 of varying lengths therein for the receptionof the left-hand end oi bars 3d, 4d, .and 5d (Figs. 1 and 2), to lockthe code printing bars 3e, 4e and 5e against aprinting operation. lComb15 has secured thereto a plate' 15a to loosely confine the code printingbars le,

, 4e and 5e in position. The other ends of the code printing bars are inclose proximity to the platen of the typewriter and are confined in acomb identical to the comb 5| previously described, excapt it isopposite hand. 'I'he ends of the code printing bars 3e, 4e and 5e havelateral thereon having a pointed portion 55 for printing bars also haveslots therein for the reception of a vertically disposed rib identicalto the rib 63 previously described for the other side of the cod.;printing mechanism. Like reference characters apply to the comb and thestructure oi' the ends of the printing bars for the right-hand side ofthe apparatus as previously described for the left-hand side."

Rising upwardly between the two combs which guide the ends of the'codeprinting bars next to the platen is the conventional type bar guide 11.Each of the code printing bars Ie to Bel'inclusive, have secured theretoone end of a tension spring 1B, whoseother end is secured to the bracket19 whose intermediate portion is secured to slide slidably mounted onbrackzt 50 by means of blocks 8| and B2. Block 82 has a projection onthe top thereof in which is threadably mounted a set screw 83 whoserearward end engages a portion 84 on slide 80 whereby the position ofbracket 19V can be adjusted to regulate the tension applied to the codeprinting bars by means of the springs 18 thereby regulating theintensity of theprinting operation of these code printing bars.

The type bars and code printing bars print by means of first engaging aconventional ribbon which is broad enough to be disposed between 'boththe code printing bars and the type printing bars on the one side andsheet 86 on the other side which is held by the platen.

Each of the code printing bars 2e, Ie and 6e has coinciding notchestherein in which a lever is adapted to project, said lever 90 beingfixed on a shaft 9| mounted in bearings 92 and 93 secured to the bracket50. Each of the code printing bars 3e, 4e and 5e also have coincidingnotches therein adapted to receive lever 94 also xedly secured on shaft9|, the purpose of said notches and levers being to normally hold thecode printing bars in a non-printing operation against the tension oftheir impelling spring 18.

The shaft 9 I has xedly secured thereon a lever which has pivotallysecured in the free end thereof a link 96 which projects downwardly andinwardly and is pivotally secured at its other end to one end of a bellcrank lever 91 which is pivoted as at 98. To the upper end of lever 91is pivotally secured as at 99, one end of link` |00 which projectsbackwardly through the printer and has its rear end pivotally secured tothe upper end of a lever IIJI which is fixedly secured to a shaft' I02mounted for oscillation between brackets I03.and |04 and normally movedtowards the rear of the typewriter by means of a tension l spring |05whose other end is secured to a suitable spring perch |06 secured to thetypewriter frame.

Brackets |03 and |04 are secured at their lower ends to a cross memberof the typewriter frame. Shaft |02 has fixed thereon near bracket |04 alever I I0 (Figs. 4 and 5), which has a roller on the free end thereof.adapted to follow a cam I I2 fixed on shaft II. Cam I| 2 has a'highside and a low side and roller III is caused to follow this cam by meansof the tension spring |05. Mounted for oscillation between the upperends of brackets |03 and |04 is a shaft II3 which hasiixed thereon alever II4 having a'roller I|5 whichis 'adapted to follow cam I2flxed'o'n shaft II and which has been previously described (Figs. 4 and6).

Shaft I I3 has iixed thereon an arm I I6 to which is secured one end ofa tension spring |I1 whose other end is secured as at |I8 (Figs. 9, 10and 11).. This spring causes roller |I5 to follow cam I2 -at all times.Cam I2 has a high point I2a, the purpose of which will be presentlydescribed.

Link |00 has a projection I I9 fixed thereto and arm IIB has an inturnedend adapted to engage projection I I9 and block the movement of link |00when it is disposed in the rear of projection II9 as shown in Figure 10,as link |00 is normally pulled towards the rear of the typewriter bytension spring |05.

While roller III is on the high side of cam I|2, the arm |00 is held inits forward position, shown in Figure l0, to relieve pressure of block|I9 on the inturned end of arm IIB. In the meantime, cam I2 is holdingthe link |00 in forward position through lever IOI to hold the codeprinting bars out of operation. After the high portion of cam I I2 ridesfrom beneath the roller I II the link |00 is pulled rearwardly by spring|05 to cause projection I I9 to engage the inturned portion of leverIIS. Then the highpoint I2a of cam I2 engages roller I I5 and shaft I I3is oscillated and arm I I6 is moved upwardly at its free end so that itsinturned portion is removed from the path of block I I9 which allows thelink |00 to move backwardly very quickly under the tension of spring |05and this moves the upper ends of levers 90 and 94 rearwardly of themachine and withdraws them from engagement with the code printing barsIe to 6e, and the spring 18 of the code printing bars moves the selectedcode printing bars quickly rearwardly of the typewriter into engagementwith the ribbon 85 to print the code of the code printing bars which reselected for operation.

It is seen hat when roller III is no longer supported by the high sideof cam I I2 that the tension spring |05 exerts rearward pressure on linkII and causes block IIS to press against the inturned end of arm II6,*so that when the high point I2a of cam I2 passes roller I I5 to movethe free end of arm IIS upwardly out of the path of block |I9, then thetension spring |05 quickly moves the link |00 towards the rear of themachine and releases the `code printing bars which have been selectivelyreleased for a, printing operation. This causes a quick movement of thecode printing bars to print the code on the sheetin the carriagemechanism.

On the opposite side oflink |00 from where block II9 is positioned,there is secured another block |20 (Figs. 3 and 9), which has a notch inthe upper rear surface thereof which is adapted to engage at times theforward end of a'lever I2I loosely mounted on shaft I I3 in closeproximity to lever IIB.

It is to be observed that there is some clearance between the upperportion of block |20 and the free end of lever I2I so that in the normalopera-7 tion of the machine, for the common code printing mechanism,which has just been described, there will be no `engagement betweenlever I2I and block |20. This will allow the code printing bars to beoperated and will not in any way interfere with such code printingoperation. However,

' there are certain functional operations of the machine which arecarried out from time to time, and at which -time there is no codeprinting operation carried'out. In such events, it is desired to blockmovement ofthe code printing bars for such functional operation.

"Ther'efcre, it is seen that there is pivotally secured near the. freeend of lever |2| a link |22 (Figs. 3, 9 and 11), which projectsdownwardly and is pivotally secured to a lever |23 secured on a shaft|25 mounted 4for oscillation between the brackets |03 and |04. The link|22 isA normally moved upwardly to hold the lever I2I in the positionshown in Figures `3 and.9 by means of tentherein and whose lower endengages aportion of the typewriter frame I0. The rear end of member |26has a pair of notches |28 and |29 cut therein so that this member |26will not in any way interfere with the conventional push bars I5 of thetypewriter, the conventional push bars I5 being connected to a type barfor a printing operation.

However, there are certain functional push bars in the machine which donot operate a. type bar but which operate certain mechanisms of themachine such as the carriage return bar I6, line feed mechanism bar I1,blot out or unshift mechanism bar I8 and bar -|9 for operating the shiftmechanism. When these special bars are operated, of course, no printingoperation is carried out, therefore, in order to prevent, by anypossible chance, a printing operation from being carried out, therelease means for the code printing bars are automatically lockedagainst movement when these special push bars are selected foroperation.

When the permutation bars to 5 inclusive, are selectively moved toselect one of the special push bars I6 to I9 inclusive, so that thispush bar is allowed to be pressed upwardly into a set of coincidingnotches in the permutation bars I to 5 inclusive, then lt ls seen thatas one of these special push bars is moved upwardly it will engage therear end of lever |26 and will slightly oscillate shaft |25 which willmove link |22 downwardly and cause the free end of arm I 2| to movefurther downwardly than is shown in Figure 9 and will block the printingcontrol link bevcause the free end of arm I 2| wlll be moved low enoughto be in the path of the lower portion o1' block |20 secured on linkf|0|l.

Special or functional push barIG, when selected, not only .oscillatesshaft |25 and blocks link |00 against operation, but also operates theconventional carriage return mechanism.

Now, it is evident, by referring to some of my above referredtoco-pending applications, that the control sheet produced by certain ofmy typewriter mechanisms,v as well as that produced by this mechanism,has the first space in a line left -blank so that an extra spacing codecharacter can be placed in this first space. Let us suppose that thismechanism is being actuated and controlled by such a control sheethaving the first Space in the line void of any shaded cell control. Thenof course, it is seen from the above referred to co-pending patentapplications, that the scanning of six blank cell controls automaticallyreturns the carriage to starting position. Now, in the present instance,if this occurred upon scanning .the blank space at the beginning of theline, itis evident that the mechanism would not be operable because uponthe scanning of the first space, the carriage return mechanism would beoperated thus getting nowhere, because it would never reach the secondspace in the line for actual scanning of the characters. It is necessaryto prevent, in the present instance, the

operation of the carriage return mechanism if all blank, therefore, itis seen that the conventional carriage mechanism has the projection I 30thereon (Figs. 3 and 4), which, upon the carriage being fully returned,to starting position, engages the free end of levers |3| fixed on theend of vertically disposed shaft |32 and normally held in the positionshown in Figure 4 by means of a tension spring |33. l

Shaft |32 is mounted for oscillation in brackets |35 and |36 secured tothe frame of the typewriter and is held in position for rotation bymeans of collar |31 disposed above bracket |35 and secured tothe shaftand the hub'of an arm |38 secured to the shaft immediately above bracket|36.

Secured on shaft |32 is a lever |39 Which'has a. pin |40 in the free endthereof penetrating a slot |4| in link |42. A tension spring |43isconnected to the end of said pin and its other end to the link |42 toprovide a resilient connection between pin |40 and link |42. The link|42 projects into the machine and is pivotally connected as at |44 tothe upper end of a lever '|45 pivoted as at |46 and having a shoulder|41 nea'r its lower end which is adapted to block upwardv movement ofthe carriage return bar I6, when it is selected by the scanning of sixblank cell controls in the first letter space of va line, therefore,this prevents the push vbar I 6 from moving member |26 and oscillatingshaft |25 and also prevents unlocking of link |00 to release the 'codebar printing mechanism. Ihe carriage return mechanism not beingoperated, the carriage is allowed to advance one space readyfor thewriting of the first character appearing in the line. Movement of shaft|32 under the tension of spring |33, except what is necessary to causeit to move to normal position to where it will engage the projection |30as the carriage is being returned to normal position, is prevented bymeans of the arm |38 engaging a stop bracket |48 -secured on bracket|36.

On the lower end of shaft |32 is secured a lever |50 which normallyrests against the rear end of lever|5| pivoted as at |53 in the rear endof lever |54 (Figs. 3 and 12). Lever |54 is pivoted as at |55 andnormally rests against the inner edge of a lever |56 which is pivoted asat 38 (Figs.

will oscillate lever |54 in a counter clockwise direction in Figure 12which will move the lower -end of lever |56 away from the machine andmove the upper end, of course, inwardly towards the machine which willmovezcode locking bar 4d into engagement with thecode printing bar 4eand lock this code printing bar 4e against a printing operation.

This code printing bar 4e prints a cell control which signifies acarriage return operation and therefore this mechanism prevents theprinting of a carriage return operation 'on the control sheet 86produced by the herein disclosed apparatus, when the carriage isstanding at fully returned position.

Connected to the basket |60 of the typewriter or printer mechanism is anarm I 6I which projects rearwardly and outwardly from the machine whichpenetrates a slot |63 in the upper end of a link |64 mounted for slidingmovement between the 'bracket 34 and a plate |65 secured to said bracket34. A tension spring |66 is secured at its ends to arm |6| and link |64to provide a resilient connection between said parts so that if for anyreason the basket' should be raised while movement of link |64 should beprevented no breakage or damage of parts'would result. This resilientconnection might be necessary because on the lower end of link |64 thereis an outturned projection |61 which is normally in a position so thatit will not block movement of the lever 6b. When a shift of the basketmechanism of the machine takes place, then of course, link |64 will bemoved upwardly to cause the projection |61 thereon to be in the' path ofa projection Y|68 secured on lever 6b (Figs, 3 and 12).

This prevents the rear end of lever 6b from following bell crank lever,6a and holds it in a position where it will hold the code locking barin unlocking position. This will allow code printing bar 6b to beactuated to print cell control 6 on the control sheet as long as thebasket.'

of the machine is held in shift position.

Figure 22 shows a portion of a control sheet produced by the hereindisclosed apparatus. The

direction of scanning is indicated by an irregular line passing throughthe cell controls. It is seen in Figure 23 that beneath each spaceprovided for avlegible charactei` there is a control area having sixspaces indicated as 6', 2', 3', 4 and 5'. It is, ofcourse, clear thatcode printing bar 6e prints in the space 6', and code printing bar leprints in the space I', and soV on.. Therefore, if code printing bars 6eand 4e are selected for a printing operation, for indicating acharacter, then of course, areas 6' and 4' for example, would have aprinted dot therein indicating these two control areas as being shaded.

When a blot out is placed on the control sheet in the transmitter, ofcourse, there would appear l' no printed matter on the control sheet 86produced by the herein-disclosed apparatus, for the sending of a blotout.

In Figure 22 no extra space code character is shown in the rst space, asthis has been fully described in some of my copending applications,-

above referred to, but of course it is to be understood that thismechanism has a type bar for the printing of the extra 'space characterin the rst space of a line, if desired, after a line has been written,but of course, the transmitter in transmitting this line would transmitthe extra spacing' character in the rst instance, because it wouldappear on the transmitting sheet but 'would be placed on thetransmitting sheet after the line has-been written and it was found thatjustification required the extra spacing characteristic, and at whichtime, of course, the extra spacing characteristic would be placed at thebetrol of other transmitters or for the -control ofl ginning of thetransmitting sheet, but the sheet produced by the herein-'disclosedprinting apparatus, of course, would produce the extra spacingcharacteristics as the first operation in a line so that this sheet 86could be used for the conlinecasting machines, type-setting machines andall other types of character. reproducing machines as set forth in myprevious co-pending patent applications 404,331; and 517,171.

Cell control area 6' is the cell control for the 'shift mechanism.- Inthe present 'arrangement of the control sheet with the cell controlsthere-- on, this sixth cell control is placed so that it will be scannediirst in the scanning of a control area for a character so that when thesheet is used in a transmitter or a type-setting machine, it will givethe shift mechanism time for operation by the time the scanningoperation of the entire control area has been completed.

In the drawings and specification there has been set forth a preferredembodiment of the invention, and although specic termsare employed, theyare used in a generic and descriptive sense only, and not for purposesof limitation, the scope `of'the invention being set forth in theappended claims.
